[asterisk-users] Two phones, same number

[Benny Amorsen]

I would like to have two phones acting like one phone. Explaining it
is a bit difficult, even though what I want is really simple.

Assume that I have two phones, a wireless and a wired phone. Both are
in the Dial(), so whenever a call comes in, both of the phones ring.
If I happen to be at the desk, I pick up the wired phone and talk. If
a second call comes in, the wireless phone will be ringing even though
I'm busy on the wired phone. I would like the second caller to get a
busy tone.

I have considered various ways to solve this. One is to make a queue,
and only allow one caller in the queue. As far as I can see this won't
work, at least not when I am busy because I did an outgoing call.
Another way is to use GROUP() to put the calls in a separate group,
and return busy when GROUP_COUNT > 0. Unfortunately I am already using
the GROUP() functionality for something different on those calls --
and it seems a call can't be in two GROUP()'s simultaneously.

Ideas welcome...
